Answer:
the question is incomplete, but I can give two examples of interest rate being higher or lower:
For example, interest rate is 6%
PV of face value = $400,000 / (1 + 3%)¹⁰ = $297,637.57
PV of coupon payments = $10,000 x 8.5302 (PVIFA, 3%, 10 peridos) = $85,302
Market price = $382,939.57
Second example, interest rate is 4%
PV of face value = $400,000 / (1 + 2%)¹⁰ = $328,139.32
PV of coupon payments = $10,000 x 8.9826 (PVIFA, 2%, 10 peridos) = $89,823
Market price = $417,962.32
